PNEUMATIC CASH-CARRIER.

SPECIFICATION forming part of Letters Patent No. 367,724, datedAugust 2, 1887.

Application tiled October '28, 1886.

To all whom, it may concern:

Be it known that I, WILLARD S. PAIN, of Cambridge, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Pneumatic Cash-Carriers, of which the followingis a full,

clear, and exact description.

This invention relates to improvements in apparatus for pneumatic eash-earriers--such for instance, as are shown and described in Letters Patent of the United States, dated December 2S), 1885, No. 333,897; and the invert tion consists, in combination with a pneumatic tube for the transmission ofa cash-carrier,&c., therethrough by the operation of any suitable bellows or air-motor, of an indicator suitably constructed and arranged for operation by Said bellows or air-motor, whereby it will in dicate whether the carrier placed in the tube for transmission thcrethrough and the bellows or air-motor operated has been transmitted through the tube and delivered or ejected therefrom at the other end, or is within the tube, all substantially as hereinafter fully de scribed.

In the accompanying sheet of drawings is illustrated the present invention as applied to a pneumatic cash-carrier apparatus con structed and arranged for operation substantially as described and shown in said patent,

Figure 1 being a perspective view of such apparatus at the cashiers desk or table or central station, with the present invention applied thereto; Fig. 2, a detail vertical section; Fig. 3, a detail vertical cross-section; Fig. 4, a detail sectional view, and Fig. 5 a detail front View. Figs. 2, 3, and 5 are enlarged.

In the drawings, A represents a cashiers desk or table or central station, from which the three pneumatic tubes B, 0,,and D lead to their respective sales counters or stations, (not shown in the drawings,) each tube being secured to the head E of its transmitting standard F, secured to the top G of the table.

II is the bellows, secured by its top board, J, to the under side of the board G, and each standard F has communication therewith by a separate pipe, K, secured to the bellowsboard K and the table-board G.

Cords L are attached to the bottom board, M, of the bellows, on each side, and respectively extend around pulleys N on the side uprights, P, and pulleys Q on a treadle, R, and secured to the uprights, the treadle being pivoted to the uprights and arranged to be operated at a at the front of the table. The lower open end of each head E of the transmittingstandards F where the carrier is inserted is closed by its valve when the carrier is placed therein for transmission through its tube.

()ther valves are arranged in connection with the bellows and the pipes leading therefrom, whereby all the tubes can be closed as to their air-comlminication with the bellows, except the tube through which the carrier is to be transmitted.

Pressing down the treadle closes the bellows, forcing air into the tube in communication therewith,causing the carrier, if placed therein, to travel through said'tnbe to its sales counter or station, all substantially as described and shown in said patent, and needing no more particular description herein.

The object ofthe present invention is,in the use of pneumatic cashcarriers, to enable the operator, after he has inserted a carrier in the tube and operated the bellows or other airmotor to transmit it through such tube to the sales eou nter or station, to ascertain at a glance whether thecarrier has been delivered or ejected from the tube at such station or is still within the tube.

Secured to each head E by an arm, I), is a I box, T, in which is asmall bellows, U, secured by its board (I to the side e of the box, its board f being free to move within the box for the proper operation of the bellows, as usual in bellows. The bellowschamberVhas com munication with the chamber 9 of the head E by a passage, h, through the board (I and arm I), as shown in Fig. 2 in section.

In front of the bellows U is a partition or board, Z, on which is pivoted at m an index pointer, XV, its lower arm, Y, having an elongated slot, a, connected to and arranged to slide over a headed pin, 1', secured at the end of the movable bellows'board f, its other arm, t, pointed at its end a, and in position for observation through an opening, Z, in the cover of the box. 011 this partition 1, at the left-hand upper corner of the opening Z, is stamped or printed the word Out, and at the opposite corner the word In! The operation is as follows: Having placed a carrier within the head E to the tube through which it is desired to transmit it, close the valve S and operate the bellows, which, through the air-pressu re, will force the carrier along and through such tube to the station at the other end and eject it therefrom. As the carrier moves along or is stationary within the tube air will pass through the passage h into the indicator-bellows U, opening it by moving its board f from its board (I, as shown in Fig. 3 in section, carrying with it the arm Yofthe indicator IV, and correspondingly moving its pointing end a in the opposite direction to and over the word In, as shown in dotted lines in Fig. 2, indicating that the carrier is within the tube, and the pointer will remain in such position so long as the carrier is in the tube and the bellows are operated; but the instant the carrier is delivered or ejected from the tube .the air has free passage from the bellows through the tube, and therefore will not then pass to the indicator-bellows U, which will im mediately close from the force of its spring 0, returning in such movement the index-pointer V to its normal position, or over the word Out, indicating that the carrier is out of or has been delivered or ejected from the tube. \Vith the carrier in the tube and the bellows H operated, its resistance to the air-pressure causes air to pass to the indicator-bellows and operate it, as described, and if the operator in working the apparatus observes that the pointer is at the word In, he knows the carrier has not been delivered or ejected from the tube, and will again and again operate the bellows until the pointer returns to the word Out, indicating the carrier has been delivered from the tube, when he ceases his operations. The indicator is placed at thehead E as a convenient place for observation thereof; but obviously it can be attached to any convenient place on the apparatus or elsewhere, it only being essential that its bellows shall have aircommunicalion with the tube or bellows or otherair-motor for the a r to pass thereto for its proper operation.

The power of the bellowsspring 1; can be adjusted to suit the force or pressure of the bellows H and the resistance of the carrier thereto when in the tube.

The index-pointer shown in Fig. 2 can be dispensed with, and a pointer or indicator arranged on or near the end of the movable board f of the bellows, as shown, for instance, in Fig. 5, which is a view in detail of such an arrangement, \V being the indicator or pointer, secured to the end of the moving board f, and projecting through a slot, [0, in theeover, the words In and Out being reversed, as shown in said figure. The figure represents the bellows in its normal position or when the tube is empty. In dotted lines the bellows is shown as open, with the indicator or pointer at the word In,

indicating, with the apparatus in operation, that the carrier is in the tube.

Any suitable form of bellows can be used, or in lieu of a bellows a common valve; or the bellows or valve can be arranged over an opcningin the tube, &c., its movements alone indicating as to the condition of the tube.

The indicator can be applied as well to the tube at the sales-counter or single station.

Although this invention is described and shown in connection with the caslrcarrier apparatus described in said patent, it is obvious it can be applied to other forms of cashearriers operated by air either by pressure or by exhaustion of the air; but when operated by exhaustion of the air the indicator-bellows should be an exhaust-bellows and the pointers be reversed in their movements, the words In and Out being accordingly changed.

In lieu of the words In and Out, any other words or any suitable indicating marks can be used, or only one used; or both may be dispensed with and the pointer be arranged to be seen in the opening when the carrier i's'in the tube,and disappear when out, or vice versa.

Having thus described my invention, what I claim is- 1. The combination, with a tube for the transu'iission of a carrier, &c., therethrough by the operation of a bellows or other airmot-or, of a pneumatic indicator having communication with said tube or bellows or other air-motor,so that the indicator, in the passage of air from or to the bellows or other airmotor as it is operated, will show or indicate whether the carrier, &c., is in orout of said tube;

2. The combination, with a tube for the transmission of a carrier, &c., therethrough by the operation of a bellows or other airmotor, of an indicator consisting of a bellows or valve having con'imnnicat-ion with said tube or bellows or other air-motor for operation thereof, substantially as and for the purpose specified.

3. The combination, with a tube for the transmission of a carrier, &c., thcrethrough by the operation of a bellows or other-airmotor, of an indicator consisting of a bellows or valve and an index or pointer connected thereto, having communication with said tube or bellows or other air-motor for operation thereof, substantially as and for the purpose specified.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
